Abstract
Abstract This invention relates to a medicament which contains a gamma-globulin preparation containing anti-e antibodies. This medicament can be used for eliminating or reducing the infectiousness of biological liquids containing antigen-e or the virus of hepatitis B and can also be administered intramuscularly or intravenously to treat hepatitis and/or acute or chronic infections caused by the virus of hepatitis B in humans and animals.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
55 words
A medicament which contains, in a physiologically acceptable medium, a gamma-globulin preparation containing an effective amount of anti-e antibodies, the said preparation being obtained from serum or blood plasma or from placentary extracts and the said preparation being free from substantially all normal blood protein constituents other than gamma-globulins and from substantially all infectious contaminants.
Claim 2
Dependent Claim
55 words
A medicament which contains, in a physiologically acceptable medium, a gamma-globulin preparation containing an effective amount of anti-e antibodies, the said preparation being obtained from serum or blood plasma or from placentary extracts and the said preparation being free from substantially all normal blood protein constituents other than gamma-globulins and from substantially all infectious contaminants.
Claim 3
Dependent Claim
24 words
A medicament according to claim 1 in which the gamma-globulin preparation has been subjected to a treatment to eliminate or reduce its anticomplementary power.
Claim 4
Dependent Claim
26 words
A medicament according to claim 2, which consists of blood, of plasma or of any other biological liquid to which the gamma-globulin preparation has been added.
Claim 5
Dependent Claim
19 words
A medicament according to claim 1 in which the said gamma-globulin preparation contains predominantly one of the anti-e antibodies.
Claim 6
Dependent Claim
20 words
A medicament according to claim 4, in which the said gamma-globulin preparation contains predominantly anti-e 1 or anti-e 2 antibodies.
Claim 7
Dependent Claim
35 words
A process for the treatment of hepatitis or acute or chronic infections caused by the virus of hepatitis B comprising administering intramuscularly or intravenously to an infected human or animal the medicament of claim 1.
Claim 8
Dependent Claim
72 words
A process for eliminating or reducing the infectiousness of a biological liquid which contains the virus of hepatitis B or antigen-e comprising contacting said liquid with a gamma-globulin preparation containing an effective amount of anti-e antibodies, the said preparation being obtained from serum or blood plasma or from placentary extracts and the said preparation being free from substantially all normal blood protein constituents other than gamma-globulins and from substantially all infectious contaminants.
Claim 9
Dependent Claim
72 words
A process for eliminating or reducing the infectiousness of a biological liquid which contains the virus of hepatitis B or antigen-e comprising contacting said liquid with a gamma-globulin preparation containing an effective amount of anti-e antibodies, the said preparation being obtained from serum or blood plasma or from placentary extracts and the said preparation being free from substantially all normal blood protein constituents other than gamma-globulins and from substantially all infectious contaminants.
Claim 10
Dependent Claim
21 words
A process according to claim 7, in which the said gamma-globulin preparation containing anti-e antibodies is added to the said liquid.
Claim 11
Dependent Claim
25 words
A process according to claim 7 in which the said liquid is passed over an immuno-adsorbent, the surface of which is lined with anti-e antibodies.
